Use Word’s built-in thesaurus to help you find synonyms of a word. For example, you can use the thesaurus to replace the ho-hum word “good” with one of its synonyms, such as “beneficial,” “capable,” or “excellent.”
Select the word you want to replace.
On the Review tab, click Thesaurus.
The Thesaurus pane at the right shows a list of words with similar meanings to your selection. If a word has multiple meanings, each meaning will have its own list of synonyms.
Hover over a new word and click the menu arrow.
Click the Insert button.
Your selection is replaced with the new word.
Close the Thesaurus pane when you’re done.
Right-click a word. Select Synonyms and then select a new word from the list.
